ROTARYLUBRICATOR.'

T0 all whom it may concern:

Be it known that I, DUNCAN L. MCCORKIN- DALE, a citizen of the UnitedStates, resi-ding in the city of Troy, in the county of Rensse- 5 laerand State of New York, have invented certain new and useful Improvementsin Rotary Lubricators i'or Journals, of which the following is aspecification, reference being had to thcaccompanying drawings.

My invention relates to improvements in lubricators that are adapted tocontain lubricating material, and to be rotated by peripheral contactwith a revolving journal to be lubricated.

The general objects of myimprovements are to provide means forregulating the rate of escape of the lubricating material from thelubricator to the journal as may be required by journals of differentsizes or of different 2o heating tendencies or by lubricants oi'different qualities or degrees of fluidity, to provide simple means forlubricating the journals of rotary lubricators, and to furnish a cheapand quickly-detachable holder for rotary journal- 25 lubricators.

In the accompanying drawings, Figure 1 is an isometricalrepresentationof one oi" my improved lubricators applied for use to a journal. Fig. 2is an isometrical drawing of one 3o end portion of the saine lubricator,the outer porous covering being removed. Fig. 3 is an isometrieal viewof the other endv portion of the same lubricator, showing a sectionthereof at the line y y in Figs. 4 and 5. Fig. 4 is a 3 5 side elevationofthe same lubricator but without a porous covering.- Fig. 5 is acentral longitudinal section of the same lubricator in the plane Vor"the line .e z in Figs. 2, 3, and 4. Fig. 6 is a central longitudinalsection at the 4o line w w in Fig. 7 of a lubricator that enij braces aportion ot' this invention, and Fig. 7 is a transverse sect-ion of thesame at the line .r ai in Fig. 6.

Like letters refer to similar parts in the dit'- 45 ferent iigures.

- A is a hollow cylinder furnished with heads B Bf, and adapted tocontain lubricating 1na terial V, Fig. 5, and having in itscircumferenceanaperture or apertures c to permit the 5o gradual escapetherethrough of the lubricat ing materialto ajournal, U, Fig. 1, to belubricated.

For regulating the rate of escape of the lubricating material fromwithin the cylinder A through its aperture or apertures c, I furnish thecylinder with an adjustable cut-off, G, arranged either within thecylinder, as shown in Figs. 6 and 7, or exterior thereto, as illustratedby the other figures.

In the lubricator shown by Figs. (i and 7 the cut-off O has perforationsd corresponding to the perforations c through the casing A, and has atits ends screw-stems e e', which extend and iit throughsuitably-arranged holes in the heads B B', and are furnished withscrew-nuts g g,which iit closely upon the screw-ste1ns and are screwedtightly against the heads. By loosening one and tightening the other ofthe .two nuts the eut-oft C can be moved and adjusted lengthwise withinand closely along the casing A, so as to thereby open or close theapertures c to any desired extent, and thereby control the rate ofescape of lubricating material through those apertures.

The cut-off Cin Figs. 6 and 7 may be aperforated bar, as shown in fulllines, or a hollow cylinder with open ends and fitting closely as alengthwise f movable sleeve within the casing A, as indicated by dottedlines at /L in those figures.

In the lubricator shown by Figs. l, 2, 3, 4, and 5 the cutoff C is inthe form of a sleeve which fits closely to and can be turned and adjusted circularly upon the cylinderA,which latter has a longitudinal rowof pcrforations, c, Figs. 3 and 5.

The sleeve or cut-ott` C in Figs. 2, 3, 4, anal 5 has a series ofperforations, d, which are y arranged in circumferential rows that areat the same distances apart as the perforations c and in lengthwise rowswhich have different numbers of perforations, and in Fig. 4 are numberedl 2 3 4 5 6 7 8 9, respectively.

In Figs. 4 and 5 the sleeve C is shown ad justed with its lengthwise rowof iiveperforations d in coincidence with live of the perlorations c inthe body of the lubricator. The sleeve is adapted to be turned andadjusted so as to have any desired lengthwise row of its perforations incoincidence with the row of perforations inA the cylinder, and therebypermit more or less of the lubricating material to escape through suchperfora'tions in a given time. The sleeve C in Figs. l, 2, 3, 4, 5 canbe adj usted circularly and retained in position upon the cylinder A `byvarious means, but as an improved device for that-purpose I have 011 onehead, B, of the cylinder a row of stops or 1o notches, z', spaced and numbered in conformity with the lengthwise rows of perforations in thesleeves, as indicated by Figs. 1, 2, and 4, and have in proper positionon the sleeve a v stop or spring-catch, j, Fig. 2, adapted to be-readily engaged with and disengaged from each of the stops or notchest' by hand.

The above-described adjustable lubricators shown by Figs. 4 and 5 and byFigs. 6 and 7 can be used to apply suitable lubricating mav2o terial tosuitably-shaped journals by having the outer surface of the perforatedsleeve C 0f Figs. 4 and 5 or the perforated casing A of Figs. 6 and 7:bear directly in contact with the journal to be lubricated. I, however,gen- 2 5 erall y surround the perforated sleeve C of Figs.

2, 3, 4, 5 or the perforated casing A of Figs.

6 and 7 by porous or fibrous material K-as,

for instance, a layer or layers of loosely felted or woven fibrousfabric-secured or 'wound aroundthe said sleeve or casing, so that suchporous or fibrous covering shall absorb the liquid or semi-liquidlubricant passing outward .through the perforations c and d, and

thereby -distribute the lubricant along and around the wholecircumference of the lubricator and journal to be lubricated as thelubricator is revolved by the surface contact with the journal.

In Figs. l, 3, and 5 the porous or absorbent 40 covering K is shown infull lines, and is indicated by dotted lines in Figs. 6 and 7.

In using the lubricator, it can be held so as to be revolved by surfacecontact with the upper, lower, or any other exposed side of a revolvingjournal by various well-known de vices. As an improved means for thatpurpose,I make the lubricator with small conical or pointed journals Z,and provide a holder, M, which is adapted to be hinged, pivoted, orsimilarly secured to a xed support, essentially as indicated at a inFig. 1, and has arms o, formed. with interior depressions orperforations, into which tit the small conical or pointed journals Z ofthe lubricator, as illustrated in Fig. 6, one or each vof said armsbeing elastic so as to thereby securely hold the lubricator by itsjournals, and allow it to be freely revolved, and also permitthelubricator to be at once removed from and replaced inthe holder uponmerely springing outward one or each of the arms` of the holder by hand.

To provide means for lubricating the small pointed or conical journal Zof the lubricator, 55 I form the latter with a perforation or passage,as at p, from the lubricantchamber to the surface of the pointed orconical journal,

and have a wick, q, extending outward from within said chamber closelythrough said passage or perforation, substantially as shown 7o by Figs.5 and 6.

ln Fig. 5 the head B is detachably secured to the cylinder A by male andfemale screws thereon, as at r, for convenience in introducing materialand in placing the sleeve or cut- 7 5 off C upon and removing it fromthe cylinder.

In Fig. 6 the head B is shown detachably secured to the cylinder A byscrews s, to permit the ready insertion and removal of the cut-off C,and is furnished with a removable screwplug, t, to allow lubricatingmaterial to be introduced into the chamber of the lubricator.

I am aware that a cylindrical journal-lubricator adapted to containlubricating material, and to be rotated by peripheral contact with arevolving journal to be lubricated, and having its circumferentialcasing perforated and surrounded by a felt or porous covering, is notnew.
